Three-way Decisions with Evaluative Linguistic Expressions
This work addresses a theoretical problem in decision-making and linguistics, but it appears incremental as it combines existing concepts without clear practical application.
The paper tackles the problem of interpreting three-way decisions using evaluative linguistic expressions from natural language, resulting in a new connection between three-way decisions and linguistic theory.
We propose a linguistic interpretation of three-way decisions, where the regions of acceptance, rejection, and non-commitment are constructed by using the so-called evaluative linguistic expressions, which are expressions of natural language such as small, medium, very short, quite roughly strong, extremely good, etc. Our results highlight new connections between two different research areas: three-way decisions and the theory of evaluative linguistic expressions.
